INK CARTRIDGE.

Original application filed March 2, 1922, Serial No. 540,488. Divided and this application filed February To all whom tf/nay concern.'

Be it known that I, BYRON B. GOLDSMITH, a citizen of the United States, residing in New York, county and State of N ew York, have invented a certain Improvement in Ink Cartridges, of which the following is a specification.

The many inconveniences anddisadvantages of transporting and storing ink in liquid form are well recognized and various ways have been proposed for avoiding them by supplying apparatus whereby solid inkproducing material might be supplied to the consumer in suoli a way as to make it possible to produce a liquid ink by the mere addition oi water when and where the ink was needed.

Dry ink powders variously compounded, and intended to be used by solution in water at, or near the time and place of use, are well known in the art; but they are awkward to use and uncertain in eiect, particularly in the hands ot the average unskilled consumer.

The present invention relates to a novel means for the preparation of ink powder of any kind 'in a manner insuring the making of ink of exactly such proportions as are deemed best in a given case, without waste of powder and practically instantaneously. At the same time my improvement provides a very convenient package for shipping the ink powder ready lor instant use, which package perit'ectly protects the powder and keeps it in condition it'or insuring perfect results when used. 'lhc invention also has the advantage that it prevents accidental spilling on hands, clothing and so l'orth.

The principal or basic element of the invention, which is claimed as novel per se, is a cartridge comprising a capsule, which may be given a variety of shapes, but is always characterized by the presence of a thin layer ot ink powder (preferably uniformly distributed) which is confined between two protective layers ot' a permeable nature, although not necessarily in contact with both layers. rlhe protective layers or either of them should be made of a permeable material such as cloth or the like.

These capsules may be combined with a supporting guiding element to vform cartridges or with appropriate vessels used as ink stands, and both ot these combinations Serial No. 619,346. v

form the subject matter of certain of the claims herein. y

This is a division of an application resulting in my U. S. Letters Patent No. 1,518,503 dated December 9th, 1924. f

Certain embodiments of this invention are illustrated by way of example in the accompanying drawings wherein Figures 1 and 11L are views partly in section and partly in perspective showing two forms of a circular capsule, Figure 2 is a sectional view of a simple form of cartridge with a removable capsule, Figure 3 is a sectional view of another form of cartridge provided with a number of capsules, Figure 4 is a view in section of a drum-shaped capsule, and Figure 5 is a view partly in elevation and partly in section showing another mode of applying the invention to an inkstand.

In the simplest form of capsule a thin layer of ink powder is spread uniformly over a sheet or layer 11 of permeable material, preferably cloth or the like, and over this is placed a second similar layer 12, the whole being fastened together at the perimeter, as at 13.

As shown in Figure 1, there may be a central permeable layer 14, having thin layers of ink powder 15 and 16 on its opposite faces, conlined in place by outer permeable layers 17 and 18.

In use, water is simply poured through a capsule of this kind and ink is produced. No shaking or stirring is required and none ot the powder can get loose to rstain the fingers, clothing etc.

In Figure 2 is shown a simple iorni ot cartridge for putting to use the simple capsule of Figure 1 or 1am This comprises a support and pouring tube 19, to one end of which the capsule can be applied so as to entirely close the opening, as shown at 20. The capsule may be applied to the tube 19 in any manner, as, for instance, by means ot the threaded collar 21.`

Where a larger quantity of ink or a more intense ink is to be made at once, a number of capsules 22 can be inserted at intervals in the main tube 19, being held apart in parallel relation by short interior friction sleeves 23, or otherwise.

In Figure 5, the inkstand has a threaded filling orifice at 31 over which A[he capsule Q0 is laid, being held in place by the lili',

removable funnel 32, screwed on over the orifice 31. `Water poured into "ille funnel will pereolate through the capsule linto'the inkstandl and be converted into ink on the way.

As shown in Figure 4, the permeable sides of the capsule need not necesarily looth'befinV I larger sizes 'with'percolating spa'cesibetween them.

The examples described above ere/sutilcient 'to vmake it -cl'eir thst 'rnany Ychanges. may be made in 'the' form "and "arrangement fthe devices vdesenleed without. departing from the scopeofthe invention whichisnot limited'to the det-ailsherein described and shown.

What is claimed isr1. An lnk ca'trldgecmprisinga Vpouring tube in combination with a capsule'closing the same comprising two or morev layers of zpermeable "materialenclosing n layer of ink powder.

f2. .An ink cartridge as in claim l wherein `one at least of the permeable layers is composed of abs'orbentimaterial.

j 3. 'An ink cartridge as in claim l wherein a plurality of ink capsules are held within the pouring tube.

4. Anfnk cartridge as in laim f1 'wherein aiplurality of'ink capsules are held 4within the pouring tube by'niea'nsiof spacing sleeves fitting fri'ctlonll-'y 'withinthe' tube.

5. Apparatus for making liquid 'zink eem-r.

prising a cylindrical pouring tube of Sub? stantially uniform bere, in 'combinationwith a, capsule containing vink "powder 'a'nd "extending completely 'across and within 'the end off'saidtube. i

In testimny whereof have lhereto set my handfon this l14 day 'of Febru'siry, 1923. BYRON B. GOLDSNHTH.
